Well the appeal to China didn't work. Instead we have a warning issued.
Personally I think Obama needs to tell S. Korea fight or surrender. But I'm sure he'll issue a 'double important' appeal to China and 'more' needless sanctions for N. Korea. Heck if he's really mad he'll send Hillary to the UN in New York for 1000 star sanctions.
